Comparative study of two Japanese rhinoconjunctivitis quality-of-life questionnaires

Abstract

The questionnaires were highly correlated in terms of both overall and comparable domain scores. In addition, both questionnaires had equal and satisfactory psychometric validity, demonstrating that they are both useful tools for assessing QOL in rhinitis. However, when compared with each other, the JRQLQ focuses mainly on activities of daily life and is simpler, while the RQLQJ focuses mainly on rhinitis-related health and is more responsive.
